It is, of course, possible to implement a UBI that is too low to make it practical to move, but I would argue that in that case, it is missing the "Basic" part, because it does not provide enough to meet real people's Basic needs.
The thing that gives "Capital" power is that you have it, no one else does, and you're trying to transform it into some arrangement that over time creates more value than it consumes.
The transformation applied can absolutely be done incorrectly, making subsequent capital value transformations more difficult to accomplish profitably given greater constraints on the means the capital allocator can bring to bear.
Nothing about UBI substantially changes the nature of that system, therefore, the real problem to be solved, (the asymmetry of means between capital allocators) given a system that optimizes toward capital control centralization (more capital fewer hands) without also being paired with wealth ceilings via tax extraction at the top and reinjection at the bottom.
Sure, that would definitely be one area where UBI would assist with but as I mentioned in another comment - it would kind of defeat the purpose of the UBI if people had to spend it on mitigating the consequences of people taking advantage of them receiving UBI
I don't have a good answer either... I just agree that UBI seems like a net positive.
Poor people don't have functional families or communities of support in a lot of cases, that's why they're poor.

It would kind of defeat the purpose of making money with a job if people had to spend their earned money on mitigating the consequences of people taking advantage of them receiving money.
So... the takeaway is strive to earn less so you get preyed on less?
I don't agree. Jobs are much more than just income. They provide purpose, skills (possibly for life and future work), experience (in general and for acquiring future work), possible medical or investment benefits, connections (social and for future work) etc. All these things mean that there are many situations where earning less or having to move would be outweighed by the benefits.
This is not the case in my example - UBI is JUST income. If the providing of UBI creates more problems and negates the income, then it loses its benefit and purpose (not saying this would be a guaranteed problem inherent to UBI, but that was the premise of the OP)
This is a pretty privileged perspective to have and shows that you may not fully grasp what it's like to be poor.
Do you understand the costs of moving (both monetary and time spent)? Do you understand the cost of most likely having to quit and find a new job (if they are available)? do you understand the costs (socially and mentally) of having to leave your community/family of support?
The opportunity cost of what you are suggesting makes it much less feasible than you make it seem
